LE BOURGET, France: Geopolitical tensions roiled the opening of the Paris Air Show on Monday (Jun 16) as French authorities sealed off Israeli weapons industry booths amid the conflicts in Iran and Gaza, a move that Israel condemned as "outrageous".

The decision added drama to the major aerospace industry event, which was already being held under the shadow of last week's deadly crash of Air India's Boeing 787 Dreamliner.

Black walls were installed around the stands of five Israeli defence firms at the trade fair in Le Bourget, an airfield on the outskirts of Paris.

"Israeli companies have signed contracts with the organisers ... it's like creating an Israeli ghetto," he said on French television channel LCI.
